Did Dublin Airport in the 1990s have a pyramid shaped touchscreen information point?

I don't remember the info point, but I do remember the Iolar replica hanging from the ceiling and a demo cockpit from a Boeing jet of some description that you could take a look in - also vending machines for sweets chocolate and crisps (WOW!) and space helmet style black and white TV screens mounted on the seat arms of plastic seats that you could put coins in to operate, also the outdoor airside viewing space on the roof of the original terminal building where you could go to wave at your relatives as they climbed the steps mounted on top of the little vans to board the planes (paid turn-style access to view, but Esso petrol station collector coins also worked). I remember being on the roof in 1971 for the arrival of Aer Lingus first 747, it flew low over Dublin to show everyone what we had got, before landing at the airport, to a musical welcome from The Army No 1 Band.

I think Ireland's NASA allocated piece of moonrock was also at the airport at one stage, viewed through a magnified glass dome placed over it on a mounted plinth.

The airport was a very exoctic and futuristic place, for a just about teenager in the mid 70's. I even went there for my 'after confirmation outing' for a meal in one of the restaurants that had a window view of the planes - we knew how to live back then :)

I'll get me coat ……

I think you mean runway 06/24 (later redesignated 05/23), which saw most 24 departures turn left over the city. Dublin never had only one runway. In those days there were three, in a triangular layout dating from the late 1940s. Some of the old charts shown here depict the layout.

My biding memory of that time is going into the terminal and airport police using the metal detector on the ladies handbags but only in departures. If you had something you could just go in the arrivals door.

But the entrance with the screening was at the lower (arrivals) level, as far as I recall.

I'm not sure what you are referring to in the potted history text. I have lived fairly close to Dublin Airport since 1972 and I can assure you that 06/24 (later designated 05/23) was the principal runway used pre-1989, with 17/35 (later designated 16/34) as the secondary and 12/30 for light aircraft, of which there were many based. Of these three, only 16/34 now remains, for use in the fairly rare event that winds or other factors rule out use of the parallels.
